To all-whom it may concern:

Be it known that 1, Earn. M. KRAMER, a citizen of the United States, residing at Paxton, in the county of Ford and State of- Illinois, have invented a new and useful Soil-Pulverizing Attachment for Plows, of which the following is a specification. I

This invention has relation to soil pulverizing attachments for plows and it consists in the nc'ivel construction and arrangement of its parts as hereinafter shown and described. v

The object of the invention is to provide an attachment of the character indicated which consists primarily of an attaching means with various adjustments and to which is connected a ulverizer having a series organg of rotating soil pulverizlng members. Means 'is also provided for adjusting the pitch or angle of the pulverizer with relation to the line of draft. Int-he referred form of the invention oppositely disposed so il cleaving blades are mounted in advance of the pulverizer and are adapted to reduce the larger clods to smaller-dimension in order that they may be eliectually operated upon bythe pnlveriser in reducing them to a'mu ch A further object of the invention is to provide means for preventing the pulverizer from having. a tendency to move or work toward the landside of the furrow when in operation.

A'still further object of the invention is to provide means for raisin the pulverizer above the surface of the soii and for simultaneously supporting the same through the instrumentality of a trailing wheel and gear. in order that turns may be readily made and that an im lement with the'attachmentjap-t plied may e conveyed from place to place.

The invention also includes various de; tails and modified arrangements as will be particularly pointed out in the. subjoined description and in connection with the drawmgs. I

In the accompanying drawings: Figure l is a perspective view looking at the side of a plow with the attachment a plied thereto. Fig. 2 is a perspective View 0 the rear portion of a-plow with the attachment applied thereto and parts thereofiremoved. F1g. 3 is aplan View of a modified ,form of pulverizer supporting arm used in the attachment. Fig. 4 is a side elevation of means for clamping the supportingba r'of the p'ul- 1 verizer to the form of arm as shownin Fig. 3. Fig. 5 isan edge elevation of one of the cleaving blades which is disposed in one d1- rection. Fig. 6 is an edge elevat'on of one of the cleaving blades disposed in heopposite direction. Fig. 7 is a perspec ve view of one of the cleaving blades detached. Fig. 8 is a side'elcvation partly in section of one form of standard which may be used upon the pulverizer. Fig. 9 is a side elevation of the upper portion of another form of standard which may be used on the PU]- verizer. Fig. 10' is a side elevation of a modified form of standard used upon the attachment. Fig. 11 is a plan view of still another form of pulverizer supporting arm for the attachment. Fig. 12 is an edge elevation of another modified form of cleaving blade, and Fig. 13 is an edge elevation of still another modified form of cleaving blade. Fig. 14 is aperspective, with parts broken away, showing how an arm used in the attachment is pivotally connected with a supporting means.

The attachment consists of the bracket 1 which is adapted to be adjustably secured by means of the clamp bolts 2 at any desired oint along the lengthof the side rail 3 of t e frame of the low or other implement to which the sai attachment may be applied. The shelf. iece is mounted upon thebracket 1 and may be'adjusted about an axis thereon and secured in an adjusted position by the clamp bolt 5 which asses transversely through the" said brac st and the said shelf piece. The shelf piece 4 is provided with an elongated slot '6. The block 7 isarranged to slide longitudinally along the shelf piece 4 and. is provided at its edges with the depending flanges '8 which receive the edges of the shelf piece 4. The post 9 is mounted upon the block 7 and may beiturned axially thereon and secured in an adjusted position by means of the clamp bolt 10 which passes transversely through the base of the said post 9, the block 7 and the slot 6 and which clamp the said post 9 and'block 7 in position upon the. shelf piece 4. The. upper end of the. 0st 9 is provided with a segment gear 11. he lever 12 is fillcrumed to the'iupper portion 'of the post 9 andis provided with a pawl mechanism13 adapted to engage the segment '11.] The. lower end of the lever 12 is formed into a gear pinion 14 which is concentric with relation tofll'o fiulorum' point of the said lever.

lane ador .friction roller is journaled upon the side of the post 9. The arm 16 is ournaled at itsfprward end in the base 0 the post 9 and 18 adapted to swing vertically or in a are t p The in 17 is adjustably mounted upon the arm 6 and the lower end of the rack bar18 asses thro h the lug 17 and is provideda a point be ow the said lug with a cotter pin 19, as shown in Fi 2, or other means may be provided for limiting) the longltudmal movement of the ,said ar with relation to the said lug. The coil sprin 20 is interposed between a shoulder carri by the bar 18 and the upper surface of the lug 17. Said springl is under tensi a with a tendency to hold t the lower sidelo f the lug 17'." he upper portion of the bar 18 lies between the eriph-f cries of the pinion '14 and the roller and is provided with teeth 21 which mesh with the pinion 14.

From the foregoing description it is obvione that the bracket 1' ma be applied at 3 of the implement. It will also be seen that by swinging the shelf piece 4' horizontally and securing the same that the forward end of the arm 16 may be moved and h d toward or away from the side of "the In lement. Also, that b shifting the block idea the shelf piece the lateral adjust- 'ment 0 the forward end of the arm 16 may '9 axially or upon the, pivot at its a angle with relation to the line of draft. Again by adj usting the lug 17 along the arm I 16 the weight of the load carried by the rear be augmented or the position of the said arm with relation to the side of the implement may be readil cadjusted'to a nicety. It will also be seen t at by turningbthe post asethat the arm 16 may be pitched at any desired end of the said arm' may be'more easily raised or lowered. The spring always T has a tendency to hold the arm 16 down so with relation to each other and the a tachment may e so positioned with relation to each other, as to engage with the frame of any pattern of implement irrespective'of its projections in that the parts of the attachs ment may be passed around or between the rejections mounted upon .the implement e, In other words the attachment is lel with that occupied by the e cotter" in 1 against any desired point fore 'or 9. along the side' "rai latio'n thereto.

insane designeil ilb he applied to im lements having any particular or usual con guration or desi of frame.

hesoil pulverizer isad'ustably attached to the rear end portion 0 the arm 16 by means of the i'clamp lates 23. a The bar 24 is pivotally connecte withthe lower clamp plate 23 and may be swun with relation thereto and secured in a esired position, The standards 25 depend from the bar 24 and the soil pulveri'zing members are mounted for rotation below the'bar, 24 and between the standards 25. ,The saidpulverizing members may be blades "or knives as illustrated in the drawings or they may be disks. By swingiggthe ar 2 4 horizontally upon its pivotal connection with the lower clamp plate 23 and securing the same the angle of itch or inclination of the ulverizing memrs maybe ad usted with relation to the line of aft of ie implement. The fender ribs 27 are carried by the pulverizer 22 and are designed to keep the ulverizing members free from the collect on of' trash, etc. Said ribs are attached at their upper ends to the bi; and bear at their lower ends a ainstt axle upon which the members 2 arefmounted and aretwisted and rearwardly bowed at intermediate portions as at 28' which said twisted rtions lie parallel with the paths describes by the said verizing members and by reason of tras which is impaled orfpicked up byt pulverizing members and area the snmebii' of and away from the said members.

ultheir h and bowed configuration will engage The bars 29 and 30 are located in advance of the bar 24 and areadjustably mounted upon the arms 16 by means of the sleeves 31 and 32 or their'equivalents. The said bars 29 and 30 are said sleevcs an may be swung horizontally and secured in an desired position with rehe soil cleaving blades 33 depend from the bar ,29 and the soil clcav ing' blades 84 dependlfrom the bar 30. The

blades 33 and 34 are'rearwardly and laterally curved toward their lower ends but the lateral curvature of the blades 33 is opposite to that of the blade 34. The said, blades are I (provided at their upper ends with for wa by the clamp means of which the angle of inclination in lateral directions of the saidbladc mayvbc readily adjusted. The clamp mountedu on t e rear end portion of the arm 16 behind the plates 23. The lug 3B is mounted upon the upper clam plate 37 and the bell crank rocker arm 38 is )ivotally connected with the said lulg 3S. lhe itman 40 pivotally connects t is plpper on of the arm 29 with the lever 12. he rear end (pivotally connected with the.

lates 3i are adjustably" ly-disposed shanks 35 which are held pl te 36 in close contact against the under sides of the bars and by pf fili e. arm 39. is provided with a substantialla 'vertically disposed bearing 41 in whic is journaled the forward end of the amifi. "The rotary moven'ient of the arm 42 in the bearing 41 is limited by means of a pin 43 attached to the arm 42 and which passes througeh an opening provided in the. uirleof the aring 41. The forward portion of the arm 42 1s substantially vertically disposed while the rear portion thereof is substantially horizontally disposed and forms a spindle 44 upon which the ground wheel 45 s journal'ed for rotation.

It will be seen that when the lever 12 is swung toward the rear the pitman 11 will be moved lon itudinally which irr turn will swing the rec er-arm 39 upon its pivot so that the rear end thereof will descend. Consequently, the arm 42 is lowered and the an wheel 45 is forced against the surce of the ground. At the same time the pinion 14 in engagement with the teeth 31 of the bar 18 will move the said bar longi tudinally and in a vertical direction which through the cotter pin 19 and lug 11 will cause the rear end of the arm 16 to swing up so that the soil cleaving blades and pu verizin' elements are raised above the surface 0 the soil. When the lever 12 is swung in'a forward direction the operation above described is reversed. Thus it will be seen that means is provided for simulthncoiisly raising the soil engaging elements is the siipporting wheel'descends and rice verse and that one lever is so calmer-ted with these parts as to simultaneously operate them. when the attachment is in operation upon the surface of the soil it is lowered into cnga ment with the same'and the ground whee 45 is raised. \Vhen making atom at the endof a furrow the pulverizing elements are raised and the ground wheel is lowered. When the implement is traveling from place to place with the attachment applied the ground wheel is lowered and serves as a support for the attachment preventing the same from having undue vibration.

The bracket 46 is adjustably mounted upon the standard 25 which is nearest the implement to. which the attachment is applied. The lower end of the said bracket is provided with an outstandin lug 47. 'lhe block 48 is pivotally mounte between the lugs 49 attached to the bracket 46. The arm 50 passes throu h the block 48 and may be adjusted therein oth longitudinally and axially and secured in an adjusted position b means of the set screw 51 which passes tirough the said block. The coil spring 52 is interposed between the upper portion of the bracket 46 and the arm 50 and under tension with a tendency to hold the upperends of the said bracket and arm apart. The lower portion of the arm 50 is laterally disposed as at 53 and has slidin connection with the arm 54 and may be fixed with relation thereto by means of the clamp bolt The wheel 56 is journaled for rota tion at the rear end of the arm 54 and is adapted to travel immediately behind the rear furrow wheel of the implement and in contactwith the angle formed at the inter-.

section of the bottom and side of the furrow.

The wheel 56 and the arms 54, 50 and bracket 46' are designed to prevent the pal verizer 2:! from. having a tendency-tomove laterally toward the landside of the furrow as it would have in the absence of these parts by reasonof the fact that the pulverizing. elements aJre pitched .at an angle to the line of draft and are convergedat their forward sides toward the landside of the furrow -By thismeans rigidity is added to the pulverizer when in operation.

' By shiftin the bracket 46 along the standard 25 the w eel 54 may be raised or lowered tooperate' in a shallower deep furrow and the vertical adjustment of the wheel 56 may be effected to a nicety through the adjustable connection of the arm 50 with the block 48'. The wheel 56 may be shifted laterally so as to properly engage the sides of the furrow and track or furrow behind the rear wheel of the implenientby means. of the slidin Y connection between the arms 53 and 54 an the clamp bolt 55. By reason of the fact that .the block 48 is pivotally mounted between the lugs49fthere is a certain amount of hinge movement between the soil pulverizer and the wheel 56 which is resisted by the coil spring 52 but which is suflicient to render the attachment suflicien tly flexible to ride over obstructions without danger of damage or excessive jarring. The hinge movement between the said parts is limited by the lug 41 formed at the lower end of the bracket 46 and which may be engaged by the, block 48 or arm 50 when the pnlverizer.

and the wheel 56 attempt to have an excessive hinge movement with relation to each other.

Fig.3 of the drawing shows a modified form of the arm 16. This arm' is especially adapted to be used when it is desired that .the outer end portionsof the bars 24, '29

and 30 shall not rock in opposite directions. That is'to say, if there is any vertical movement of the said parts it shall be uniform 'tliroughout and not with one end of the part ascending while the other end thereof is descending. In this form of the invention the arm 16 proper is veryshort or what is enerally'termed a stub extending from its forward end to about the point indicated by i the arrow 57 in Fig. 1. The said stub 16 fits into the sleeve 58 and is secured therein by means of the set screw 59. The tubular branches 60 connect with the sleeve 58 and are pitched at an angle to each other with,

held therein by means of the bolts 66.

their rear ends diverging. The arms 61 are titted in to the rear ends of the branches 60 and are held therein by means of the set screws 62. Thus the rear portions of the arm til diverge. The sleeves 63 are slidably mounted upon the arms 61 and may be secured in an adjusted position by means of theset screws 64. The lower portions of the sleeves (53 are provided with parallel jaws (ifrwhich are adapted to receive between them the bars 30, 29 or 24 and which are It is of course understood that two sleeves 63 are required for each of the said bars they being'applied one at each end of the said bars. It. is obvious that by shifting the sleeves (13 along the arms 61 out of transverse aiinement with each other the said bars may be pitched at any desired angle with relation to the line of draft.

Fi 8 illustrates a modified form of standard 25. In this form of standard the lower end thereof may be connected with the axle upon which the pnlverizing memlnus are mounted at oints between the said members. This is esirahle in some cases e pecially where the pulverizer is long and should need bracing at its middle. In-the said form the lower end of the standard 25 is-provided with a bearing 67 which is provided at its ends with the bosses 68. The oil hole 69 passes through the said bearing. The sleeve 70 is located in the bearing and surrounds the axle rod 71. The washers 72 are provided with annular flanges 73 which" receive the bosses 6S and which bear against the sides of the pulverizing members 26 or their equivalents. Thus the flanges 73 form dust guards at the ends of the bearing while at the same time an adequate support for the intermediate portion of the axle is provided.

.\t the upper ends of the standards shown in Figs; 8 and t) twoditferent' or modified forms ofmcans for connecting the standards with the bars 24 are illustrated.

The form of standard as shown in Fig. 10 is curved or bowed rearwardly .to conform to the general shape of the intermediate bowed portions of the ribs 27. Thus the said standard serves as itilsupport and a fender.

In the form of blade as shown in Fig. 12

the shank 35 is dispensed with and the upper 'cnd of the blade is provided with a laterally disposed portion 34 which is b'olted to the bar 30.

In the form of blade as shown in Fig. 13, the upper end of the blade 33 tits in the lower portion of the block 74. The block is provided upon its upper side witha rounded portion 75 which bears against the under side of the bar 29. The bolts 76 pass transversely through the bar 29 and the lugs 77 at thesidesof the'block 74 and'may be adjusted so that the slant of the blade 33 with relation to the bar 29 may be pitched at a desired angle.

In the form of arm connectingmeans as shown in Fig. 11, the sleeve 58 is spaced from the branches (30 and the said branches 00 are open at both ehds so thatthearms 61 may be adjusted hmgitudinally therein to any desired extent.
